A way to avoid unwanted new lines when using paragraph quotes?

A way to avoid unwanted new lines when using paragraph quotes?

Hi, folks —

First of all, many thanks to the contributors for their work on
Org-Mode.  I'm a happy (novice) user; first time poster here. :-)

I have a seemingly trivial aesthetic problem. I've attached the
reproducer .org file and its HTML export to demonstrate it.  I'm sure
advanced users might recognize the problem immediately. As you notice
in my HTML export: An unwanted new line is added between "Test 3" and
"sub bullet under test 3, with a quote" (which uses
BEGIN_QUOTE/END_QUOTE in the .org file). Likewise, a new line is added
before "Test 4" starts.   And yet again, a new line under "Test 6" and
its sub bullet.

Is there a way to avoid the said new lines in the above mentioned
examples? (NB: A space right _before_ the quote starts is okay.)  Or
alternatively, is there a way to consistently force a new line in the
HTML export, after each of "Test 1", "Test 2", et al?

Many thanks in advance!

Regards,
Kashyap

A solution could be to 'force' a homogeneous space between all the items
of the list by modifying the 'margin' property
(https://www.w3schools.com/cssref/pr_margin.asp).

For example:

#+HTML_HEAD: <style> li{margin: 15px;}</style>

Hi Kashyap,

The problem seems to be that when the HTML exporter finds more than one
element within a list item, it wraps each one in its own set of
=<p>...</p>= tags, which creates the additional space. You can see that
this has nothing to do with the quotes, just inserting a second paragraph
within the list item triggers this, e.g.:

------
3. Test 3
   - sub bullet under test 3, with a quote:

     another paragraph within the bullet
------

As Juan Manuel suggested, one way to fix the visual difference is with CSS.
To be more selective, you could style only <p> items with a <li>, like this:

#+HTML_HEAD: <style>li p { margin: 0em; }</style>

In my test, this eliminates the spacing before those items, making them all
look the same in the browser.

Looking at the ox-html code, there doesn't seem to be a way to prevent this
from happening at the moment, a plain paragraph is always wrapped in <p>
tags.

Hope this helps,
--Diego

Ah, I see.  So it's any element within a list item that's wrapped in
paragraph tags.

Hmm, that fixes the new line before the "sub bullet under test 3, with
a quote".  However, a new line still remains after the quote ends (and
before the "Test 4" starts).  Is it possible to nuke that too?  If
not, that's okay, I can live with it. :-)

Thanks for taking the time to look at the code.

I'd say a vertical space before and after a block quote would be
'typographically' correct. But if you want to eliminate the space after
the block quote, without having to modify it in a general way, it could
be solved with a bit of Elisp, by defining a custom filter so that the
<blockquote> tag would be modified only within a plain list. Thus, with the
configuration that Diego has suggested, everything would be without
vertical space except the space before each block quote:

#+BIND: org-export-filter-plain-list-functions (my-filter-html)
#+begin_src emacs-lisp :exports results :results none
    (defun my-filter-html (text backend info)
    (when (org-export-derived-backend-p backend 'html)
      (replace-regexp-in-string "<blockquote>"  "<blockquote style=\"margin-bottom:0px\">" text)))
#+end_src

Regards,

Juan Manuel

You're right, and I agree.

Thank you for the code snippet. My only use of Emacs is Org-Mode, so I
haven't spent much time learning Elisp yet.

That should be possible with CSS as well, but as I'm not a CSS expert, I'll
leave it for you to figure out :)
